Overview

The DIM12 is a low voltage 12V or 24V PWM lamp and LED dimmer module controlled by the supplied external potentiometer.

Connections to the DIM12 are shown in the Connection Diagram section. The DIM12 is connected to the supplied external potentiometer module with 2-core cable. Turning the potentiometer shaft clockwise will increase the lamp brightness, anti-clockwise will decrease the lamp brightness. The DIM12 features a fail-safe feature whereby in the event of an open circuit between the DIM12 and the potentiometer module, the output will default to full brightness. The dimming control can be any resistance such as a thermistor - for temperature controlled dimming, or an LDR - for light controlled dimming. 0R = fully off, 10k = full brightness.

The DIM12 can be used with any 10k linear potentiometer. Only two terminals of the potentiometer need to be connected to the DIM12: the wiper (central) terminal and left-most terminal with the shaft facing you.
